[ANN] cudaMiner & ccMiner CUDA based mining applications [Windows/Linux/MacOSX]

[th00ber]

Any ideas on how to monitor hash rate with ccminer running in background on linux?

I have a switching program that moves pools by stopping and starting ccminer. I don't have any display output though (eg; stdin and stderr both go to /dev/null)

Is there way to monitor what the cards are doing in terms of hash rate and temperature?

redirect stdout+stdin to a file instead /dev/null. you can truncate the file periodically to avoid excesive growth.

Yes that should work, but I am using Python's Popen to start ccminer and funny things happen with stdout etc.
However I will give that a go and see what happens.
I was hoping there might be another command somewhere that would report stats :-(

Thanks

If you want, I have made a bash script that check the ccminer output (I have redirected the output in a file) and periodically parse it.
I can check it directly in the commande line, and I update a webstatus page.
Webstatus : http://th00ber.no-ip.biz:8045/rigstat.html
Outputcheck script: (it's a my "screen -r" like display, to remember when I was using sgminer in BAMT with my Radeon )

Code:

  GPU 4 hashing at 8660 Kh/s

yeah, sometimes I miss myself.

Welcome back Christian!

I am struggling with something silly using ccminer with python (on linux) and I am sure you will know the answer:
I am using subprocess.Popen to start ccminer, and I redirect stdout to a file, *BUT* I am getting nothing in the file and still getting all the output to the screen :-(
My C programming is even worse than my python (and that's bad) but it looks like the applog function is writing to something other than STDOUT?
Or at least subprocess.Popen doesn't recognise it as STDOUT?
Any clues?

bigjme,

What do you have in store for cudamining.cc as some of the next features?

Can we get a CUDA Utils/Other page?

We could put:
1) Link to drivers and miner version needed
2) OC utils here plus some cool stuff like
3) Links to things like CCManager and KB's Profit Calc

Yes. Split screen must be now in category "cool stuff like CCManager anf Profit Calc"

MAYBE.

I think it would be great to have a link at the top of the RELEASE page for the miners.   It might be a "util" but it works with the miners so it goes in both groups IMHO.  It should work with EVERY current miner release so it sort of defies category.  It used to be a miner but now is even better with the current implementation.  So maybe the current release could be on the "utils" page but a hard coded link is on the release page with a brief description and link to the utils page?!?!

Sort of best of both worlds.

What do you guys think?

HEY! don't tell me how to code

drop me a PM with an image of what you mean so i get a proper idea, adding it in paint will do..... i guess  

Lazy Ass!

We don't care about no stinking framework.  We just want Utils page.

Oh and how to compile under LINUX FAQ too.

Hey im all up for incentive donations.... anyone?..... no?  
I will get it added once i know what people want. The compiling under linux... not so easy as i don't have a linux system now

A start for 'Compile under Linux FAQ':

Based on Linux Mint (Ubuntu clone) x86-64:
- install >340 driver from nvidia or your distro repository
- install nvidia_uvm driver from your distro repository
- install CUDA toolkit 6.0 from nvidia
- downloaded current ccminer source from github (e.g. cbuchner1, djm34, tsiv)
- autoconfig.sh
- configure --with-cuda=/usr/local/cuda-6.0
- make -j <number of your CPU cores> (e.g. make -j8)
- export LD_LIBRARY_PATH=/usr/local/cuda-6.0/lib64
- export PATH=$PATH:/usr/local/cuda-6.0/bin
- ccminer -a x11 -benchmark

In case of runtime errors make sure:
- nvidia and nvidia_uvm modules loaded into kernel you can add 'nvidia_uvm' string to /etc/modules to have nvidia_uvm loaded automatically during start
- /dev/nvidia, /dev/nvidia0 exist. Should be created by kernel modules
- /dev/nvidia_uvm exists. Can be created with:
sudo mknod -m 660 /dev/nvidia-uvm c 250 0
sudo chmod o+rw /dev/nvidia-uvm

If you want quick compilation (for compute_50) modify Makefile.am: change all compute_30/sm_30 into compute50/sm_50 and get rid of compute_35/sm35 strings. It has to be done before running autoconfig.sh.
Thanks to that compilation takes ca 15 minutes but ccminer will work only on maxwell cards with compute 5.0.

i still have virus adh.2 going to remove and then reinstall drivers  

[bigjme]

ps how many hits do you get a day? on http://cudamining.cc/url/releases?

i didnt bother to build in a hit counter as i didnt expect it to honestly get used much xD
i may build one in just to see lmao. Why did you ask? I don't have ads if that's what anyone thinks lmao, the site runs entirely off donations. right now, it hasn't had much

That's a great tip - so much quicker! Thanks

How will a GTX780Ti perform MH/s wise on X11?

When you start the process, try to add "2> /somewhere/ccminer.log", that is how I get the output of my background ccminer in my linux rig

between 5.5 and 6MH depending on OC

Just picked up a 750 ti, first time mining with an nvidia card. Mining x13 getting around 1950 khs. Just wondering what normal is for the 750 ti.

IIRC that's a perfectly normal hashrate on a 750 Ti for X13.

Thanks for the response, just wanted to make sure everything was working right. New to ccminer, a lot less tweaking done it seems. I managed to get it up to 2025 khs with a lil oc, then realized I was locked in pcie 2.0 in bios changed that to 3.0 was worth another 25kh. Now if I could only sell my 270's I could run a full rig of 750 ti's.

You can sell them easily i guess

Experts and experienced programmers,

I want to add some effort to ccminer development. Can you help me and point where to start ? I have some C/C++ experience but have never used CUDA.

Thanks in advance.

You've come to the right place then! 
Perhaps you should also join #ccminer @freenode IRC.

Thanks baton...we need more people like you who have the ability and want to learn how to contribute to the cuda compute mining software arsenal

I wish been trying to get rid of them. Seems a lot of people around me are, 270's sitting at $100 a piece, 280's at $175. I've been watching those 280's on craigslist for some time now, they get much cheaper and I might snag 2 for gaming. Nothing is moving around here everyone thinks once you mine with them that they are trash.

i still have virus adh.2 going to remove and then reinstall drivers  

just got my computer going again flickers on and off. still didnt get the virus out yet and the btc wont confirm bjm34. i can hardly use the computer again. im going nuts  
EDIT:im going to leave those 788 drivers in and worry about the virus.

From all I have read, I think you should wipe out everything and reinstall (and vice versa)...

[bigjme]

If you can, download a linux boot disc and get off your bitcoin wallet. And blank it using Linux.

That is taking that your main os is windows and you have no wallet backups

Thanks for the help. Christian dropped me an email with a hint. Basically ccminer is writing to STDERR and not STDOUT. I was only redirecting STDOUT and doing nothing with STDERR. That sorted it. Your comment is exactly right for people using bash shell, but I was doing it within python. For bash  2>&1  would do the trick (redirecting STDERR to STDOUT)

All working now. Ta
